Tyra is the female leader of the bike gang in IL036: The Bridge Bike Gang. Since she was a beautiful girl Brock couldn't help but flirt with her in which she told him to beat it. She battled Misty and it seemed like her Cloyster was the winner. She knew Jessie (or "Big Jess" as she was called). Later she and the rest of her gang helped Ash and co. get the medicine to a sick Shellder. Brock still wanted to go out with her but she gave him a slap on the face instead.
